I tried the same statements (on Mac) and I cannot reproduce the problem.
Anyway, note the logic:
NATIVE_IMPORTER = __builtin__.__import__
...
def custom_importer(name, globals=None, locals=None, fromlist=None,
level=-1):
....
return NATIVE_IMPORTER(name, globals, locals, fromlist, level) # line 87
So basically the custom_importer is doing nothing but delegating the
native_importer (__builtin__.__import__) with the same arguments.
If you have any idea please let me know. If you can give me access to the
server I can try some debugging.
